Hi Benjamin, Thanks for the reference. I originally wanted to open an fd in userspace as suggested, but the alq(9) API did not support that. I guess I'll try adding a new alq creation function for this purpose. Similarly, geom did not support that as well. I guess I'll spend sometime on adding that infrastructure.
